Ua li no, molar mass ntawm KAl so4 2 yog dab tsi?
Cov Lus Teb. Cov khoom xyaw muab KAl ( SO4 ) 2 yog potassium aluminium sulfate. Nws muaj ib tug poov tshuaj atom, ib tug txhuas atom, ob sulfur atoms thiab yim oxygen atoms. Cov molar loj poov tshuaj, txhuas, sulfur thiab oxygen yog 39.10 g / mol, 26.98 g / mol, 32.06
Qhov thib ob, 12h2o yog dab tsi? Alum, los yog potassium aluminium sulfate, yog cov tshuaj sib xyaw nrog cov mis KAl (SO4). 12 H2O. 12 H2O ) yog tov nrog 'chrome alum' (KCr (SO4). 12 H2O ) ces cov crystals yuav muaj xim liab.
Ua kom pom qhov no, qhov molar loj ntawm alum yog dab tsi?
474,39 g / mol
Koj txiav txim siab molar loj li cas?
Ntsiab Lus
- Cov molar loj yog qhov loj ntawm cov khoom siv tshuaj lossis tshuaj lom neeg (g) faib los ntawm cov khoom (mol).
- Cov molar loj ntawm ib qho compound tuaj yeem suav tau los ntawm kev ntxiv cov qauv atomic masses (hauv g / mol) ntawm cov khoom siv atom.
